Earth Joins the Galactic Federation

History entered the twenty-sixth century, and humans began to immigrate to Mars on a large scale. In the following more than a hundred years, Mars experienced a highly prosperous civilization. Humans carried out large-scale transformations of several terrestrial planets and larger satellites in the solar system, making these planets successively become human homes. Humanity sent a team of robots to fly out of the solar system and met humans on more than 20 planets of the Galactic Federation on Centauri A. The aliens returned to the earth with the team of earth robots. Just when humans on Earth were preparing to join the Galactic Federation, the Earth encountered and was penetrated by a neutron star, and Earth's civilization was destroyed. Humans on planets that are members of the Galactic Federation reached out to help and rescued more than 10 billion earth residents. With the support of humans in the universe, humans on Earth rebuild their homes and lead a new life.
